[PATCH 320/320] ipl: Ensure no GCC builtins replace string functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



With GCC 10, the ipl is built with the compiler overriding local
definitions of some string functions, causing the ipl to trigger an
HPMC. Fix this by setting the -fno-builtin compiler flag.
